A bit of an old thread – but does anyone on here know the actual “resolution” of the 70mm print? Like if you COULD compare it to a digital res like 4k or 8k, what would it be?
This is actually something I’ve always wondered myself.
It’s probably around 4k worth of perceivable detail, although I’m not sure exactly at what point in the photochemical chain the OT films were blown up to 70 from 35.
There was actually a study done years ago where it was estimated a 35mm release print was only projecting about 875 lines worth of detail onto the screen at the absolute most.
70mm is a perf taller than 35 and roughly twice as wide, but that still only gets you between 2k and 3k worth of information up there on screen.
There’s way more detail to be gleaned from the camera negative itself, but seeing a Star Wars movie in 70mm back in the day was getting you as close as possible to what the 35mm cameras captured.
